Pages -vs- Posts

I just upgraded to 2.1 with no real issues, except for 1 small change from what i can tell. I was using a snippet to show recent posts in my sidebar, came with the original theme i believe. Now, rather than just showing my recent articles that i wrote, it also includes Pages in the list, such as News or About. Did something change in the architecture that would cause that to now show pages as well? I lost the old code i had and tried the recent posts plugin from https://mtdewvirus.com/ with the same results. Any ideas?
